Gabatarwa
Ruwa mara launi, mara wari, bayyananne, ruwa mai danko mai hygroscopic.Yana da dadi mai yaji.Solubility ɗinsa yana kama da na ethylene glycol, amma ƙarfinsa ga hydrocarbons ya fi ƙarfi.Diethylene glycol na iya zama miscible da ruwa, ethanol, ethylene glycol, acetone, chloroform, furfural, da dai sauransu Yana da immiscible da ether, carbon tetrachloride, carbon disulfide, madaidaiciya sarkar aliphatic hydrocarbon, aromatic hydrocarbon, da dai sauransu Rosin, shellac, cellulose acetate. kuma yawancin mai ba su narkewa a cikin diethylene glycol, amma yana iya narkar da nitrate cellulose, resin alkyd, polyester resins, polyurethane, da yawancin rini.Flammable, ƙananan guba.Samun abubuwan sinadarai na gabaɗaya na barasa da ether.
Hanyar Ajiya
1. Ajiye a wuri mai sanyi da bushe.Tabbatar da samun iska mai kyau a cikin bitar.
2. Nisantar wuta da tushen ruwa.Ajiye daga oxidants
Amfani
1. Yafi amfani da gas dehydrating wakili da aromatics hakar sauran ƙarfi.Hakanan ana amfani dashi azaman sauran ƙarfi don nitrate cellulose, guduro, maiko, tawada bugu, mai laushin yadi, wakili na gamawa, da kuma cirewar coumarone da indene daga kwal ɗin kwal.Bugu da kari, diethylene glycol kuma ana amfani da matsayin birki mai hadaddun, celluloid softener, antifreeze da diluent a emulsion polymerization.Har ila yau, ana amfani da shi don roba da resin plasticizer;Gudun polyester;Gilashin fiber;Carbamate kumfa;Samar da lubricating man danko inganta da sauran kayayyakin.Ana amfani da shi don guduro polyester na roba unsaturated, da dai sauransu.
